Who operates this site
Happy Land operates this project information website and provides enquiries through 0903475802 and Zalo at the same number.
Preparing an enquiry
The form prepares text on your device only. There is no customer database and the form is not submitted to a server. You can edit the message before sending it yourself. Please do not enter sensitive information.
Clipboard and external apps
Copy uses the clipboard when your browser permits it. Zalo opens a conversation where you can paste; WhatsApp may receive the prepared text in its link when you choose to open it. The external service’s policies then apply.
Optional visitor analytics
Only after you allow it does Google Analytics 4 measure page views and clicks to call, Zalo or WhatsApp. Data may include the page, language, contact channel and technical/cookie information processed by Google. We do not send names, messages, form contents or WhatsApp link addresses. Page URLs omit query strings and fragments; referrers include only the origin. A contact click does not mean an enquiry was sent or a sale completed. Google Signals, user-provided data collection, advertising personalisation and automatic enhanced measurement are disabled.
Changing your choice
Declining analytics leaves all content and contact options available. Use “Analytics choices” in the footer to change your decision. The choice is stored locally for up to 180 days; analytics cookies are set for up to 90 days. Withdrawal stops measurement and removes analytics cookies in this browser, but does not automatically delete data already sent. Contact Happy Land about data requests.
Hosting services
Vercel serves the public website. Infrastructure providers may process technical logs to deliver and protect it. External services such as Google, Zalo and WhatsApp apply their own policies.
Information already sent
If you have sent information in a messaging app and wish to ask about its use or deletion, contact Happy Land in that conversation.
